Reader-mostly synchronization schemes, such as rwlocks and RCU, aim to maximize parallelism among readers, but many existing designs either cause readers to contend, or significantly extend writer latency, or both. This paper attributes such a problem to the lack of a fast consensus protocol between readers and writers, by which the two parts cooperate to obey the semantics of a synchronization construct...
In this paper, we analysed the status of WLAN security. According to the weakness of the most common encryption protocols WEP and WPA, an attack algorithm named Predictive Judgment adapted to cloud computing environment was given. With comparing the attacking processes on cloud computing platform and traditional platform, we proposed that the attacks supported by cloud computing have become serious...
Deploying multimedia streaming over IP Multimedia Subsystem (IMS) can enable all kinds of user equipments to enjoy unified streaming service, without considering the differences of heterogeneous accessing methods. The combination of IMS and peer-to-peer (P2P) may help operators (especially telecommunication operators) to provide more scalable multimedia streaming. In this paper, we propose PMSAI,...
A web service security analysis model based on program slicing is proposed, which can be used to find existence of critical information disclosure vulnerabilities and proliferation of such vulnerabilities in a web service net, and eventually improve protection of critical information. Web service protocol is analyzed to obtain external service interfaces; source code is sliced to obtain interface...
